FLOW REGULATION DEVICE FOR BREATH ANALYSIS AND RELATED METHOD

摘要

A breath capture device for determining the concentration of acetone in a breath sample from a user. In some embodiments, the device includes a controller programmed to use stored data to control flow of a breath sample into an analysis chamber as the user exhales into a port. In other embodiments, the device includes a switch responsive to an action by the user that is operable between a first orientation in which breath entering the port preferentially travels through a second flow path and a second orientation in which breath entering the port preferentially travels through a first flow path. In still other embodiments, the device includes a flow regulator both responsive to user action and operable from a first position in which breath entering a port preferentially travels through a second flow path to a second position in which breath entering the port preferentially travels through a first flow path.

主权项

1. A breath capture device for collecting a breath sample from a user, comprising:
an influent flow port; a flow path coupled to the influent flow port, the flow path comprising a chamber; a memory configured to store data based on at least one characteristic of the user, the data generated before the user exhales the breath sample into the device; and a controller programmed to use the data stored in the memory to control the flow of a portion of the breath sample into the chamber as the user exhales the breath sample into the influent flow port.
